C#条码生成及打印实例代码

这篇文章主要为大家详细介绍了C#条码生成及打印实例代码，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

本文实例为大家分享了C#条码生成及打印的方法，供大家参考，具体内容如下

?
string BarcodeString = "13043404455";//条码
  int ImgWidth = 520;
  int ImgHeight = 120;
 
  //打印按钮
  private void button1_Click(object sender, EventArgs e)
  {
   //实例化打印对象
   PrintDocument printDocument1 = new PrintDocument();
 
   //设置打印用的纸张,可以自定义纸张的大小(单位：mm).  当打印高度不确定时也可以不设置
   //printDocument1.DefaultPageSettings.PaperSize = new PaperSize("Custum", 585, 800);
 
   //注册PrintPage事件，打印每一页时会触发该事件
   printDocument1.PrintPage += new PrintPageEventHandler(this.printDocument1_PrintPage);
 
   //开始打印
   printDocument1.Print();
 
   //打印预览
   //PrintPreviewDialog ppd = new PrintPreviewDialog();
   //ppd.Document = printDocument1;
   //ppd.ShowDialog();
  }
 
 
  //打印事件
